This self-calibrating feature requires typically 300 ms to complete and is repeatable to within ±3 µV on successive calibrations. The technique involves the extraction and digital storage of the key offset-nulling information. This information is retained without degradation as long as the circuit is powered. This eliminates the need for continuous chopping of the input signal to refresh the offset information. Once the process is complete, the bulk of the calibration circuitry drops out of the signal path and shuts down. This minimizes or eliminates any effect the calibration circuitry might have on the desired signal path. It also allows the TLC4502 TLC4502 to be used exactly like any other operational amplifier after the calibration cycle is complete. The TLC4502 TLC4502 is a high-performance operational amplifier fabricated in a 1-µm 5-V digital CMOS technology. It achieves very high dc gain, as well as excellent power supply rejection ratio (PSRR) and common-mode rejection ratio (CMRR). It uses a mixed-mode (analog/digital) internal compensation loop with digital storage of the offset information and a current-mode output to reduce its input offset to < 50 µV. The TLC4502 TLC4502 also features a rail-to-rail output structure capable of driving loads to 1 k and 1 nF. Unlike existing commercially available low-offset high-precision amplifiers, the TLC4502 TLC4502 needs only a single 5-V supply, requires no trimming, and uses no bipolar transistors or JFETs.

A nested Miller topology is used for frequency compensation. functional block diagram (during calibration) VDD POWER-ON RESET S R Q Q ENABLE COUNTER RC OSCILLATOR RCO ­ CAL CLOCK RESET DAC SAR CORE AMPLIFIER + LPF RCO During the calibration procedure, the operational amplifier is removed from the signal path and both inputs are tied to GND. The class AB output stage features rail-to-rail voltage swing and incorporates additional switches to put the output node into a high-impedance mode during the calibration cycle. Small-replica output transistors (matched to the main output transistors) provide the amplifier output signal for the calibration circuit. The TLC4502 TLC4502 also features built-in output short-circuit protection. The output current flowing through the main output transistors is continuously being sensed. If the current through either of these transistors exceeds the preset limit (60 mA ­ 70 mA) for more than about 1 µs, the output transistors are shut down to essentially their quiescent operating point for approximately 5 ms. The device is then returned to normal operation. If the short circuit is still in place, it is detected in less than 1 µs and the device is shutdown for another 5 ms. The offset cancellation uses a current-mode digital-to-analog converter (DAC), whose full-scale current allows for an adjustment of approximately ± 5 mV to the input offset voltage. The digital code producing the cancellation current is stored in the successive-approximation register (SAR). During power up, when the offset cancellation procedure is initiated, an on-chip RC oscillator is activated to provide the timing of the successive-approximation algorithm. To prevent wide-band noise from interfering with the calibration procedure, an analog low-pass filter followed by a Schmidt trigger is used in the decision chain to implement an averaging process. Once the calibration procedure is complete, the RC oscillator is deactivated to reduce supply current and the associated noise. The key operational-amplifier parameters CMRR, PSRR, and offset drift were optimized to achieve superior offset performance. The TLC4502 TLC4502 calibration DAC is implemented by a binary-weighted current array using a pseudo-R-2R MOSFET ladder architecture, which minimizes the silicon area required for the calibration circuitry, and thereby reduces the cost of the TLC4502 TLC4502. 2 POST OFFICE BOX 655303 · DALLAS, TEXAS 75265 TLC4502 TLC4502, TLC4502A TLC4502A, TLC4502Y TLC4502Y Advanced LinEPICTM SELF-CALIBRATING (Self-CalTM) PRECISION DUAL OPERATIONAL AMPLIFIERS SLOS161A SLOS161A ­ OCTOBER 1996 ­ REVISED NOVEMBER 1996 description (continued) Due to the performance (precision, PSRR, CMRR, gain, output drive, and ac performance) of the TLC4502 TLC4502, it is ideal for applications like: D D D D D D D Data acquisition systems Medical equipment Portable digital scales Strain gauges Automotive sensors Digital audio circuits Industrial control applications It is also ideal in circuits like: D D D D D A precision buffer for current-to-voltage converters, a/d buffers, or bridge applications High-impedance buffers or preamplifiers Long term integration Sample-and-hold circuits Peak detectors The TLC4502 TLC4502 self-calibrating operational amplifier is manufactured using Texas instruments LinEPIC process technology and is available in an 8-pin SOIC (D) Package.

have true differential inputs, and remain in the linear mode with an input common-mode voltage of 0. The TLC4502 TLC4502 has a standard dual-amplifier pinout allowing for easy design upgrades. Large differential input voltages can be easily accommodated and, as input differential-voltage protection diodes are not needed, no large input currents result from large differential input voltage. Protection should be provided to prevent the input voltages from going negative more than ­ 0.3 V at 25°C. An input clamp diode with a resistor to the device input terminal can be used for this purpose. For ac applications, where the load is capacitively coupled to the output of the amplifier, a resistor can be used from the output of the amplifier to ground. This increases the class-A bias current and prevents crossover distortion. Where the load is directly coupled, for example dc applications, there is no crossover distortion. Capacitive loads, which are applied directly to the output of the amplifier, reduce the loop stability margin. Values of 500 pF can be accommodated using the worst-case noninverting unity-gain connection. Resistive isolation should be considered when larger load capacitance must be driven by the amplifier. The following typical application circuits emphasize operation on only a single power supply. When complementary power supplies are available, the TLC4502 TLC4502 can be used in all of the standard operational amplifier circuits. In general, introducing a pseudo-ground (a bias voltage of VI/2 like that generated by the TLE2426 TLE2426) allows operation above and below this value in a single-supply system. Many application circuits are shown which take advantage of the wide common-mode input-voltage range of the TLC4502 TLC4502, which includes ground. In most cases, input biasing is not required and input voltages that range to ground can easily be accommodated. 20 POST OFFICE BOX 655303 · DALLAS, TEXAS 75265 TLC4502 TLC4502, TLC4502A TLC4502A, TLC4502Y TLC4502Y Advanced LinEPICTM SELF-CALIBRATING (Self-CalTM) PRECISION DUAL OPERATIONAL AMPLIFIERS SLOS161A SLOS161A ­ OCTOBER 1996 ­ REVISED NOVEMBER 1996 APPLICATION INFORMATION R1 R2 R3 R4 R5 R6 90 k 9 k 1 k 1 k 9 k 90 k V(REF)+ V(REF)­ Gain = 10 Gain = 100 Gain = 100 Gain = 10 VDD 0.1 pF 8 2 6 ­ 1/2 TLC4502 TLC4502 RP 3 VI1 ­ 1/2 TLC4502 TLC4502 1 5 + + 7 VO+ VO­ 4 1 k RP VI2 1 k + 10) V + 100) V (Gain (Gain O O + + * VI2 1 ) R4 R6 R5 ) V(REF) Where R1 + R6, R2 + R5, and R3 + R4 ) V *V 1 ) R5 ) R6 ) V I1 I2 (REF) Where R1 + R6, R2 + R5, and R3 + R4 R4 V I1 Figure 33.
